ANTISLIPPING DEVICE.

SPECIFICATION forming part of Letters Patent N0. 697,135, dated April 8, 1902.

Application filed March '7, 1901. Serial No. 50,256. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID M. BEARING, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Antislipping Devices for the Prevention of Slipping, of which the following is a specification.

Myinvention relates to improvements in antislipping devices operated in conjunction with a shoe or boot sole constructed of yielding or elastic material; and the object of my invention is to insure a secure footing to the wearer of boots, shoes, overshoes, and similar articles while traveling on ice and other slippery surfaces. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a flexible winged-disk antislipping device. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a sectional view of the same embedded in a shoe or boot heel, as shown on lines X X, Fig. 4. Fig. 4 is the bottom of a boot or shoe heel, showing the winged-disk antislipping device contrally placed in the heel thereof. Fig. 5 is a button or rivet. Fig. 6 is a sectional view of the slotted and resilient concave wingeddisk antislipping device shown on lines X X, Fig. 4. Fig. 7 is side elevation of a boot or shoe in the sole and heel of which is inserted the winged-disk antislippin g device shown by dotted lines. Fig. 8 is a circular plate through which from the center outwardly the metal is cut, forming brad-like points. Fig. 9 is a side elevation of'a circular winged-disk antislipping device with brad-like points projecting downwardly. Fig. 10 is a side elevation of a circular winged-disk antislipping device with a threaded screw attached to the bottom thereof.

Similar letters refer to similar parts throughout the several views.

vA is a cup-shaped disk made of resilient material with slots cut in the shell or wall thereof from the rim downwardly toward its center and dividing the upper part of the above-mentioned disk into resilient wings. Upon the base of said disk is mounted the rivet or button a or its equivalent. This said resilient winged disk with the said rivet or button mounted thereon is embedded in the outer or wearing surface of a sole or heel (1, preferably made of rubber or caoutchouc, which provides an elastic and yielding surrounding for the support of the above-mentioned resilient winged disk. Referring to Figs. 1 and 3, it will be noticed that a space intervenes between the button a and the base of the disk A. It is obvious that as the resilient winged disk A is incorporated in the above-mentioned rubber heel (the outer edges of said wings slightly projecting from the wearing-surface thereof) the space between the button a and the base of the disk A is also filled with the surrounding rubber, thereby firmly securing the said disk in said lheel. In practice I perfer to leave the interior of the said disk free from the rubber that surrounds the exterior, so as to allow greater resiliency to the divided portion of the shell of said disk,(which I have heretofore designated as wings.) I also prefer to place directly beneath and against the back of the button Ct a firm substance, such as leather, to provide a firm backing for the same, or the button a could be made of somewhat larger diameter in proportion to that shown in the drawings, so as to secure the results herein explainedthat is, the button a, being of a larger diameter, the backing for said button could be of rubber, as the enlarged surface of the button resting against a rubber backing would practically be equivalent to a button of small diameter resting against a backing of leather.

It is obvious that as the weight of the wearer of a boot or shoe is brought to bear upon the resilient winged disk A through the button a (when incorporated in a heel, as herein described) the outer portion of the rubber heel 0 scribed, without in the least departing from the spirit of my invention.

Having described my invention, what .I claim, and wish to secure by Letters Patent, 1s-

1. 'In an antislipping device, the combination with a section of a rubber heel, of a cupshaped disk composed of resilient material, said disk divided by slots or kerfs into wings and embedded and retained in said heel, so that the edge of said cup-shaped disk shall project below the surface of said heel, substantially as described.

2. In an antislipping device, the combination with a section of a rubber heel and a cup-shaped disk composed of resilient material, said disk divided by slots or kerfs into wings, of a base mounted upon said disk and embedded and retained in said heel, so that the edge of said cup-shaped disk shall project below the surface of said heel, substantially as described.

3. In an antislipping device, the combination with a rubber heel of a cup-shaped disk composed of resilient material, said disk divided by slots or kerfs into wings, and means for retaining said disk when embedded in said heel, so that the edge of said cup-shaped disk shall project below the surface of said heel, substantially as described.
